Ah FeMo-co! One of the cooler cofactors - iron-sulfur cluster, plus a molybdenum, and finally a bridging carbon (https://en.wikipedia.org/wiki/FeMoco)
So yes, I can understand why it took so long to calculate the energetics of the system:
"This makes measuring FeMo-co’s ground-state energy extraordinarily complex. There are more than 78,000 plausible configurations the electrons might be in"
